Watched a bit of his video about how much he earns and the part where he mentions grad salaries of his peers definitely seems exaggerated - he says that those who did law or economics almost instantly started making 6 figures whereas medicine takes longer. Whilst it's true that medicine generally takes longer to build up income, I remember seeing data about the average UCL grad salaries (believe it was from the ONS or IFS but don't have it to hand, if anyone knows what I'm talking about feel free to link) which gave the average salaries after leaving (I think it was 1 year after?) where the range was roughly £18k to £30k, with medicine at the top followed by economics (£29k), don't remember law but it's probably not representative given that a lot of lawyers take a humanities subject and then a GDip. Law would take longer as an LLB doesn't qualify you to be a lawyer without a training contract (which often have ridiculous competition ratios), and it would probably be a couple of years until you made 6 figures anyway with either of those degrees in almost any job (even in investment banking I think it takes 2-3 years and that's a highly competitive area which very few grads can actually go into). The idea that even a significant proportion of a cohort of econ/law grads make 6 figures *almost instantly*, even from a top uni, is misleading.
I think one problem with medtube in general is how money is talked about: it's either seen as the sole focus of pursuing medicine or denied as being a factor at all (I'm hoping to pursue GEM and even the salary for F1/F2 doctors, which I've heard used as a reason why you shouldn't go into medicine for the money, is a far cry from my household income growing up)
